. To all whom it may concern A Be it known that I, OLINTO SoRoI, of

Canastota, in the county of Madison, in'thei State of New York, have'invented new and useful Improvements in Gluing-Wachines,

of which the following, taken in connection with the accompanying drawings, is a full, clear and exact description. I

This invention relates to certain improvements in gluing machines adapted to be used .more particularly by cabinet makers for applying glue to the edges of wooden parts which are to be glued together.

The main object is to render the work of gluing the edges of cabinet pieces more expeditious and uniform and at the same time to avoid waste of the glue by supporting the wooden piece in such a position relatively to,

the glue containing vat that any excess glue which may be. applied to the edgethereof will fallback into the vat. 1 V p The other objects and uses relating to specific parts of the device will be brought out in the following description.

In the drawings y Figure l is a perspective view of a gluing machine embodying the various featuresof my invention.

F 2 is a longitudinal vertical sectional view of the same. taken on line 2+2, Fig. 1.

Fig. 3 is a transverse vertical sectionalj 'or steam to keep the chamber 3 in a heated condition, particularly while the machine is in use. V

The upper compartment 4l is open at the top and forms a reservoir in which a suitable quantity of glue is maintained and to which water may be added as required through a pipe 6.

The entire receptacle may be supported in 7 any suitable manner as, for example, centrally upon a standard 7 a portion of which is shown in Figs. 2 and 3. A rock shaft8 is lournaledin suitable bearings 9 upon the. opposite ends of the vat 1 or chamber l'and upon this shaft is secured a brush +10 to rock therewith,

the bristles as ;-1l of said brush, being extended into the compartment l so as to wipe in a straight lineaeross or in close proximity tothe upper face of the partition 2. The shaft 8 and its brush 10. are adapted to be rocked forward and backward by means ofa hand crank''l2 which is secured to one end ofsaid shaft at the outside of. the vat "1.

The arc ofmovementof the brush pref- Y erably limitedto approximately 90 or from a vertical position to nearlya horizontal position into and out of the-liquid glueiindicated by thedotted line in Fig.- 3. n v

A pair ,of guide brackets -13 are m'ounted in spaced relation upon the upper edge of oneside of the vat .-l and are ad: justable 7 toward and from each other and held in their adjusted position by set screws 14l,for 'receiving and supporting the wooden .pieces,'as ;a, the edges of which correspondingfaces ofthe adjacent wall 'Of the vat to which they-are secured and are preferably inclined upwardly from their in,

nerendsso as to'support'the pieces to be glued in a similar inclined position, the

lower. rear ed es of saidbraces bein provided with stop" shoulders. or abutments braces. These stop shoulders are within the arc of movement of the free ends of the bristles -11.- of the brush 10 and are disposed in a plane substantially parallel to the axis of movement of said brush so that when the latter is rocked from its vertical position toward the horizontal position, as shown by dotted lines in Fig. 3, the free ends of the bristles 11 will convey the glue from the compartment 4- to the lower rear edge .of the piece 'a-- to be glued with a wiplng motion and owing to the fact that the glued edge is within the compartment it is evident that any excess glue which may be applied thereto will fallback into said compartment to avoid waste. The abut-* cally the entire length of the edge to be glued to contact with the brush.

positions. This movement of the brush to the work It is customary to glue large numbers of similar pieces in succession and in order that they may be properly supported during the gluing operation, they are providedwith is limited by a stop 18 which is secured to one of the bearings 9 and projects into the path of the main body or back of the partition at one side of its axis of movement as shown more clearly in Figs. 1' and 3. What I claim is 1 LA luin device com )risin a vat hav ing a horizontal partition some [distance from thebottom and top of the vat dividing the latter into lower and upper compartments'; means for heating the lower compartment, the upper compartment being adaptedto contain a quantity of liquid glue a brush journaled in the opposite ends of the upper compartment for rocking movement into and out of theliquid glue, means for operating the brush, a pair of brackets adjustable one in relation to the other along and upon the upper edge of one side of the vat for supportingthe article to be glued with a portion thereof in the path ofmovement of the brush. 1 j

2. A gluing device of the character described, the combination of a vat having a heating chamber and a liquid glue containing chamber, a brush journaled on the vat to move about an axislengthwise' of the vat and having its bristles movable intoand out of the liquid glue, a pair of brackets adj ustable along and upon the upper'edge of one side of the vat and extending into the glue containing chamber for supporting the article to be glued with a portion thereof in the path of movement of said bristles.

3. In a gluing machine the combination with a substantially rectangular glue-containing receptacle, a brush movable in" the receptacle about an axis parallel with'one of the lengthwise sides thereof, guide brackets for the article to be glued extending downwardly and inwardly across the upper edge of said one ofthe sides of thereceptacle, and secured thereto in an inclined plane",

said brackets having stops at their inner edgewise of said article adjacent toan'd be tween the stops as the brush moves about its axis.

4. A gluing machine comprising a glue containing receptacle, a gulde, for the work to be glued inclining upwardly and outwardly from the interioroii' the vat across the upper edge of one side of the receptacle and provided with stop shoulders wholly within the vat against which the edge of the article to be glued may rest, a brush mounted on the vat'to swing across the inner edge of said article when resting against said stops, and means for operating the brush.

In witness whereof I have hereunto set my hand this 22'day of J ulyf191Q.
